Can't obtain an actual IP address.No DCHP&DNS

Running XP and cannot obtain an actual IP address nor detect DHCP and DNS-I keep being assigned a private IP which is also the the same addy as the Default Gateway. I do not have a router. I've reinstalled drivers, then hit up ipconfig: DNS released, renewed,flushed and registered.Used WinsockXPFix and that was no help either. I ping'ed 127.0.0.1 and got the same successful feedback as my other laptop which is running 7 and doing great: 0% loss. I'm now I'm at a loss. Any ideas or feedback would be greatly appreciated! Again, I do not have a router. I have Comcast cable and never once had an issue switching the cable back and forth. Thanks! Maggie.
